No, the best solution is just to use protondb and see if it works there, and read some comments. Then try it. Performance really doesn't matter for most titles because generally speaking the first problem is "Does it work under Proton or not" and then "Does it work reliably." You can get the Proton build of Wine a number of ways like Lutris, from what I understand, or just install Steam on Linux.

Again, do not read what anyone says as gospel, check the games you have and want to play even if people say they're perfect. Lots of things work but a lot of high-profile stuff still doesn't, so it won't work for everybody. And if a game requires 20 minutes of fucking around to get working reliably, it's very possibly not worth it; but IME people who desperately want to use Linux will excuse any amount of issues except for literally not being able to boot.[1] For example, Dragon Ball FighterZ and Destiny 2 don't work well under Proton (for different reasons) but ultimately, I have to use Windows as a result, no matter what anyone says here. Lots of games do work on my Steam Deck though, so that's nice.

[1] You can find tons of reports on ProtonDB like the following: marked "Playable", but then it says "You must launch the game with a custom environment variable to boot it, then it will crash every 10 minutes, which sucks, but it's playable." Literally the definition of "not playable" by any metric...
